Excel 2021 has a few new functions, namely, XLOOKUP, LET, XMATCH, and a couple of dynamic Array functions. We will discover these in the following topics.
New dynamic array functions
In the previous chapter, we introduced the FILTER
and UNIQUE
functions. The FILTER
function is part of the new dynamic array formulas in Excel 2021. When we apply this function, the results spill from a single cell into the adjacent cells.
